Looking for a high performance brake rotor but don't want the expense of crack inducing cross drilled versions? Look no further as these gas slotted rotors give you the performance that even the Indy Car drivers are using. These special slots relieve the gas that gets built up between the brake pad and rotor. This "breathing" is a necessity for aggressive braking applications to get the most out of your cars braking system. Each slot also tends to "scrape" the pad and keep unwanted brake dust from building up between your pad and rotor.
